TofaZZ whom it may concern:

, the following is a specification.

- and the sector This invention relates to priming apparatus for internal combustion engines, the object in view being to provide simple eX- peditiously operable apparatus of the character referred to which may be manipulated successfully without lifting the hood which covers the engine and without the operator leaving his seat in the machine.

A further object of the invention is to provide apparatus of the character referred to which embodies such simple and economical construction that it tured and sold at small cost and readily applied to any multiple cylinder internal combustion engine.

With the above and other objects in view, the invention consistsin the novel construction, combination and arrangement of parts. as will hereinafter be more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a side elevation partly in section conventionally showing a multiple cylinder inter nal combustion engine with the priming apparatus of this invention applied thereto. Fig. 2 is an enlarged sectional view through one of the priming valves and the parts adjacent thereof showing the valve in its normal closed position. Fig. 3 is a similar view showing the position the valve assumes when in readiness to receive fuel and relieve compression. showing the position the valve assumes in priming the cylinder. Fig. 5-is a detail elevat'ion showing the operating handle or lever withwhich it coiiperates.

Referring to the drawings A designates generally a multiple cylinder internal combustion engine which is conventionally shown as comprising the cylinders B, C designating the dash of an automobile and D the fuel supply which, if desired, may consist of the ordinary fuel tank under the front seat of the machine or in any other location desired.

In carrying out this invention, a fuel feed pipe 1 extends from the'fuel supply tank D along the top of the several cylinders B may be manufac- Fig. 4c is a similar section movable across a segment 14 'ing where it is provided with branches 2 leading to a series of valve casings 3 in which the priming valves are arranged. In connection with the cylinders I employ a series of valves 4 having their longitudinal axes arranged in a common plane as indicated in Fig. 1, each of said valves being 15 rovided at its opposite ends with longitudinally ex tending stems one of which, in the preferred embodiment of this invention, is terminally slotted as shown. at 5 to receive the adjacent end of the stem at the opposite end of said valve, the stems of two adjoining valves being connected for simultaneous rotation by means of a pin 6 shown in the form of a split cotter pin for convenience and to facilitate the ready assembling of the parts of the priming apparatus. Each valve 4 is provided in one face thereof with a fuel cavity or pocket 7 adapted to contain a suit able amount of liquid fuel for priming the respective cylinder. cavity 7 the valve is further provided with a compression relief passage 8 which extends transversely through the sameat an oblique angle, one end of the passage being arranged in transverse alinement with one end of the cavity 7 so that both the passage 8 may be placed in communication with the pipe or nipple 9 which leads'from the valve casing 3 into the adjacent cylinder. The opposite end of the passage 8 is adapted under one position of the valve 4: to register with a'vent 10 in the valve casing 3 so as to permit any compressed air or gas to escape from the cylinder immediately associated therewith. The valve casing 3 is also provided with a gas inlet port 11 to Which one of the branches 2 of the feed pipel is connected. The stem of the valve nearest the dash C is extended through handle or lever 13 which is V secured for convenience to the dash C and provided with three notches 15, 16 and 17 into which the operating handle or lever 13 is adapted to snap so as to hold said lever fixed.

In order to prime the cylinders, the operathandle or lever 13 is moved from the intermediate position shown in Figs. 1 and 5 to one of the notches 15 or 17 so as to bring the cavity 7 uppermost to receive a charge of fuel and under this adjustment of the valve, the relief passage 8 registers with the priming inlet of the cylinder and also an operating Patented Au as, rain.

, Innddition to the cavity 7 and the an opening. .12 1n the dash as shown and 1s provided with roe , operator the vent 10 of'the valve casing. This releases any compressed gas in the cylinders. The operating handle or lever 13 is then turned to the extreme limit of its movement in the opposite direction which imparts a half turn to the valve 4 and brings the charging cavity 7 into communication with the priming inlet connection 9 of the cylin der, the priming liquid flowing then into the combustion chamber of the cylinder. The operating handle or lever 13 is then restored to its middle position whereupon thevalve is closed and the cylinders are all primed and ready for ignition, The engine may then be started by any of the usual methods.

It will'be observed that the priming of the cylinders takes place Without the necessity of lifting the hood which covers the engine and also without t 'e necessity of the dismounting from his seat in the machine. He may successively prime the cylinders of the engine as frequently and rapidly as may be necessary in getting the engine started.

What I claim is Priming apparatus internal combustion engines comprlsmg a series of axially alined priming valves, longitudinally alined stems for said valves connected to each other for simultaneous turnxing movement, valve casings for said valves attached to and commumcatmg With the respective cylinders, a feed pipe leading from the fuel supply to said valve casings, and means for turning said valves, each of said valves embodying a fuel cavity in one side and a compression relief passage adapted to for multiple cylinder,
